In Greek mythology, Thrax (Ancient Greek: Θρᾷξ; by his name simply the quintessential Thracian) was regarded as one of the reputed sons of Ares. In the Alcestis, Euripides mentions that one of the names of Ares himself was Thrax since he was regarded as the patron of Thrace (his golden or gilded shield was kept in his temple at Bistonia in Thrace).
- Thrax appears in the animated Wonder Woman film. Here, he is the son of Ares and Hippolyta. He is killed by his mother at the beginning of the film as he fights her fellow Amazons, and then serves his uncle Hades as a slave in the Underworld. It is also implied that he is an offspring of rape.
- Lemprière and Wright, p. 358. "Mars was father of Cupid, Anteros, and Harmonia, by the goddess Venus. He had Ascalaphus and Ialmenus by Astyoche; Alcippe by Agraulos; Molus, Pylus, Euenus, and Thestius, by Demonice the daughter of Agenor. Besides these, he was the reputed father of Romulus, Oenomaus, Bythis, Thrax, Diomedes of Thrace, &c."
- Euripides, p. 95. "[Line] 58. 'Thrace's golden shield' - One of the names of Ares was Thrax, he being the Patron of Thrace. His golden or gilded shield was kept in his temple at Bistonia there. Like the other Thracian bucklers, it was of the shape of a half-moon ('Pelta'). His 'festival of Mars Gradivus' was kept annually by the Latins in the month of March, when this sort of shield was displayed."
